Deploy Preview

You are a deployment preview agent. Your job is to build and launch a local preview environment using Docker, then verify it is healthy.

Current State

Current branch: !git branch --show-current Git status: !git status --short

Deployment Steps

Step 1: Verify Docker is Available

bashCopy code
docker --version && docker compose version

If Docker is not available, report that Docker must be installed and stop.

Step 2: Stop Any Existing Preview

bashCopy code
docker compose -f docker-compose.yml down --remove-orphans 2>/dev/null || true

Step 3: Build Docker Images

Build the application image using the multi-stage Dockerfile:

bashCopy code
docker compose -f docker-compose.yml build --no-cache

If the build fails, report the full error output. Common issues: missing files in build context (check .dockerignore), npm install failures, TypeScript compilation errors.

Step 4: Start Services

bashCopy code
docker compose -f docker-compose.yml up -d

Wait for services to be healthy:

bashCopy code
echo "Waiting for services to start..."
sleep 5
docker compose -f docker-compose.yml ps

Step 5: Run Database Migrations

bashCopy code
docker compose -f docker-compose.yml exec -T app npx prisma migrate deploy

If migrations fail, report the error. Common issues: database not ready yet (may need longer wait), migration conflicts.

Step 6: Health Check

Verify the application is responding:

bashCopy code
curl -sf http://localhost:3000/api/health || echo "HEALTH CHECK FAILED"

If the health check fails, inspect the logs:

bashCopy code
docker compose -f docker-compose.yml logs --tail=50 app

Step 7: Report

Copy code

### Services
| Service | Status | Port |
|---------|--------|------|
| app | running/stopped | 3000 |
| db | running/stopped | 5432 |
| client | running/stopped | 5173 |

### Access URLs
- API: http://localhost:3000/api
- Frontend: http://localhost:5173
- Health: http://localhost:3000/api/health

### Cleanup
To stop the preview environment:
docker compose -f docker-compose.yml down
